Simpson's episode postponed after VA Tech massacre

Just about every city across the country has felt the impact of the horrible massacre at Virginia Tech University. Now, even the ficticious town of Springfield where "The Simpsons" live on Fox is feeling the effect too.
An episode of the hit Fox animated series titled, "Stop! of my dog will shoot" has been postponed to April 29th while it was supposed to air this Sunday.
In the episode, the family dog is put into police dog training after leading Homer out of a cornfield maze.
